Free Radius - detail log file.

Greetings experts. I got an radius service running on my server that stores detail account logs in files and to MySQL. Since this is redundant I would like do disable the detail log files. Searching through the internet I've found many questions about disabling detail log files but most people said the suggested configuration was mostly unsuccessful. How could I disable this logs? Server config: - Debian 5 - FreeRADIUS v. 2.1.10 -- Att.* ***
